I have quit Tren forever 4 or 5 times now, it seems like a poison that builds up in your system over time.
It is not for newbies or idiots, works excellent for getting cut and looking amazing I usually run it @200mg per week or 300mg for a bit but for 6-10 months at a time sometimes a year I bet.
No negatives for me until I feel trashed and worn down then I drop everything except 200-250 mg of test per week until I feel better usually 5-6 months off of it
Leave it alone until you have earned your stripes for a few years at least.
